Hi,

this is my u-boot configuration:

Question: why is my board info printed twice with one bdinfo ?

I used mkimage to convert the /home/MFM/linux-2.6.x/arch/nios2nommu/boot/compressed/vmlinux.bin generated using hippo&#39;s buildroot:

* with a gzip compression: gzip --best vmlinux.bin

and:

./mkimage -d vmlinux.bin.gz -A nios2 -O linux -T kernel -n "Welcome to uClinux with MFM" -a 01100000 -e 01100000 -C gzip vmlinux.img

Another question: I&#39;ve set the bootfile and loadaddr variables and saved the environment, I type first time only tftpboot to load the kernel, but the second time I get this 

==> tftpboot
Using MAC Address 08:00:3E:26:0A:5B
*** Warning: no boot file name; using &#39;C0A8003E.img&#39;

Filename &#39;C0A8003E.img&#39;.
Load address: 0x1100000
Loading: *T 
TFTP error: &#39;File not found&#39; (1)
Starting again

and I got to type the full command tftpboot 1100000 vmlinux.img to make it work.

Is there any explanation ?

PS: I&#39;m working with the GtkTerm terminal
